TRUNK-LOCK.

SPECIFICATION forming part, of Letters Patent No. 744,532, dated November 17, 1903.

Application filed May 15, 1903.

to which it appertains to make and use the same, reference being had to the accompanying drawings, and to figures of reference marked thereon, which form a part of this specification.

The objects of this invention are to provide for trunks, sample-cases, and t-helike a hasplock which is simple in construction and which can be automatically closed without the use of a key, to at the same time secure a positive locking of the trunk or case, and to obtain other advantages and results, some of which may be referredto hereinafter in connection with the description of the work-' ing parts.

- The invention consists in the improved trunk-lock and in the arrangements and comhinations of parts of the same, all substantially as will he hereinafter set forth, and finally embraced in the clauses of the claim.

Referring to the accompanying drawings, in which like numerals of reference indicate corresponding parts in each of the several figures, Figure l is a View of my improved lock mounted upon two meeting portions ofatrunk or case, an end portion of the hasp being broken away to show the interior construction of the look more clearly. Fig. 2 is a face view of thekeeper for the lock; and Figs. 3,

i 4-, and 5 are detail views of theloeking-bolt,

showing the same in plan, reverse plan, and side elevation, respectively.

In said drawings the reference-numerals 1 2 indicate portions of two meetingmembers of a trunk or case of any kind to which my look can be suitably applied. To one of said portions, as 1, is applied the keeper or receiving-plate 3 of my lock, which is preferably stamped out of sheet metal and applied by rivets 4 at the opposite ends thereof, as is common in the art. To the other portion 2 of the trunk or case is applied an attaching- Serial No. 157,238. (No model.)

plate 5, having hinged to itself, as at 6, a hasp or tongue 7, adapted to overlie upon the oppo-' site member 1 of the trunk. Said hasp 7 carries at its inner faceasmall cylindrical lock- 5 casing 8, secured thereto by suitable rivets or screws passed through its rim, as at 9, and which is adapted to enter a correspondinglyshaped recess or seat '10, stamped in the keeper-plate 3, above referred to. When locked, therefore, the hasp member 7 of the upper lock member lies fiat upon the front surface of the lower member 3, all as is common in the art, and needs no further explanation here. Within the said lock-casing 8 is a rotary bolt 11, projecting through a central aperture in the bottom of the casing and at its inner end forming a key-receiving stem 12 in proper alinement with a keyhole in the front of the hasp member 7. Just inside its bearing 13 in-the floor. of the casing 8 the bolt is reduced and made angular, as at 14, to receive a rotary plate 15, which lies upon the floor of the lock-casing and turns with the bolt, being preferably riveted thereon. Said plate-15 has upon itself a studor shoulder 16 to be engaged by the bit of the key as the same is inserted upon the extremity 12 of the locking-bolt 11, and thus as the key is turned the plate 15 and locking-bolt 11 turn together.

The limits of such turningmovement are determined by the length of a segmental re cess 1-7 at one edge of the plate 15 and which at either end of itself forms a stop adapted to engage on each side of a fixed stud 18 on the fl'oor of the lock-casing, as shown in Fig.

1. A spiral spring 19, extending from said stud l8 and being attached to the plate 15, serves to hold the said plate, as shown in Fig.

l, and the locking-bolt, therefore, in locked position, as will be hereinafter described.

The outer or exposed end of the lockingbolt 11 is enlarged, as at 20, to provide a shoulder to lie against the outer side of the lock-casing 8, and beyond said portion 20 the lock-bolt has a head 21 extended at opposite sides of said portion 20 or transversely, as shown in Figs. 3 and 4. Said extensions are beveled at opposite corners of-their outer ends, as at 23, both transversely of the lockioo head and also inwardly toward theextremity of the bolt, so that pressure upon said faces will tend to rotate the bolt against the spiral spring 19.

In the floor of the recess 10 of the keeperplate 3 is an aperture 24 to receive the transverse head 21 of the locking-bolt, which has just been described. Said aperture, however, is arranged out of alinementwith the normal position of the locking-bolt head 21, as shown in Fig. 1, so that as said head lies in looking relation to the keeper it will overlap and engage the opposite edges of the aperture 24:, as shown. The locking-bolt must then be freed by turning it with a keyinto alinement with the aperture 24; but in closing the lock the beveled shoulders 24 of said bolt-head enable the same to snap into locking relation upon a slight pressure, as will be understood.

It will be seen that the construction described is very simple and can be made up and placed on the market at asmall cost. In fact, the Whole device consists only of the bolt 11, rotary plate 15, and small spiral spring 19. Said spring, as has been stated,

is attached at one end to the same stud which limits oscillation of the plate 15, and at the other end it is attached to the plate, preferably by means of striking up a lug 5 from said plate.

Having thus described the invention, what I claim as new is In a lock of the character described, the combination with a casing having a centrally apertured floor, of a locking-bolt rotatably mounted in said aperture and having at its outer end a transverse head and at its inner end forming a key-stern, a rotary plate fixed upon the inner portion of said locking-bolt and lying parallel to the floor of the lock-casing and having a segmental recess in the margin, a key shoulder or stop upon said plate, a single stud upon the fioor of the lock-casing projecting into the said segmental recess of the rotary plate and adapted. to engage either end Wall thereof to limit turning of said plate and a spiral spring attached at one end to said stud and extending across the plate on the opposite side of the central locking-bolt from the key-shoulder and being attached at its other end to said plate.

In testimony that I claim the foregoing I have hereunto set my hand this 31st day of April, 1903.
